<p><span id="label">Definition:</span> Information about the signer’s public key needed to validate the digital signature.</p>
<p><span id="label">Notes:</span> To validate a digital signature for an object, one first recalculates the message digest for the object, and then uses the public key of the signer to verify that the value of the signature (signatureValue) is correct. The repository must therefore have the public key value and some assurance that it truly belongs to the signer.</p>
